UNITED STATES SIMEON C'. LAWLOR, OF CHICAGO, ILLINOIS.
VALVE.
Application filed september s, 1925. sel-inno. 54,881.
My invention relates in general to improvements in valves and more specifically to an outlet valve of improved design, the action of which will be positive and which will not be impaired or caused to leak b-y the presence of grit and other particles in the fluid passing therethrough.
Considerable difhculties have been encountered where a valve is used to control the flow of a fluid containing grit or other substances which either prevent proper seating of the valve or cause wear in the valve, which eventually renders the same ineffective. This is especially true of sliding or gate valves. f
Among the objects of my invention are, therefore, to provide a valve of improved construction whichwill effectually close irrespective of grit or sand.
To provide a valve having a. plunger element which is operated by the force of the fluid pressing against the plunger to open the valve and which isi eifectually clamped against the valve seat to maintain the valve closed.
Other objects of my invention and features of improvement in the valve of my invention willy be apparent from the following detailed description.
Referring to the `accompanying draw.- ings Fig. 1 is a top view of the valve of my invention with its operating element clamped in closed position.
Fig. 2 is a view taken from the bottom of Fig. 1 with the casing shown in cross sectionv along the line A-A and showing the plunger or valve closingelement in full.
Fig. 3 is another view taken from the bottom of Fig. 1 with the plunger shown in operated position and the valve consequently open.
v Fig. l shows a modified form of clamping device for the valve.
Fig. 5 shows another modified form of clamping device.
Referring now to the various figures of the drawing, in which like parts are correspondingly numbered, I show the valve of my invention in the form of a coupling which may be attached to a reservoir as an outlet or drain to control the flow of fluid from the reservoir. The coupling containing the valve is formed as a casing 2 having a cylindrical opening therethrough threaded at one end at 3 for attachment to a pipe or reservoir. An
outlet port is formed in the lower side ofl drical plunger 5 which is shown in the form f `of a casting of any desired metal such as bronze or brass. The plunger 5 has solid front and rear walls with web flanges connecting the two and carriesa gasket 6 on its inner end fitting against the valve seat 7. On its outer end the plunger 5 has a rib or handle 8 extending diametrically across the outer' wall .of the cylinder and extending beyond the circumference of the cylinder at one end.
The rib 8 has a slantingor angular edge 9 and is engaged by a swinging arm 10 which 1s pivoted in a bracket 11 on casing 2 so that when 1t engages the slanting surface 9 of rib 8 it forces the plunger v5 into the casing and valve is shown in open position inFig. 3, and this figure shows the slot 13 forinedin the plunger 5' and a screw 141 which passes through a threaded hole in the casing 2 and projects into the slot or channel 13 to limit the outward movement of the plunger. Thus it will be seen that the plunger 5, as shown in Figs. 1 and 2, is held with the bulkhead formed by the gasket 6 against the valve seat 7 by means of the arm -10 pressing down and against the angular surface of the rib 8. This effectually prevents the flow of liquid from the threaded opening 3 through the outlet port L1.
In opening the valve it is only necessary to lift the arm 10 and rotate it in a counter clock wise :direction to release the plunger 5. l/Vhen plunger 5 is thus released the force of the liquid against the gasket 6 is enough holds the valve closed as shown in Fig. 2. The i i to force the plunger 5 out as shown in Fig. 3
and permit free flow through the port l. The outward movement of plunger 5 is, of course, limited by the engagement of the screw 14 with the inner end of the channel 13.
In Fig. 4 I havev shown a different form of locking device in place of the arm 10 of Fig. 1. This modication consists of a curved arm 16 pivoted on both sides of the casing 2 -by means of screws and having a boss 17 acting as a. handle. The arm 16 in this case is simply lifted to permit opening of the valve and when lowered hol-ds the valve closed by engagement with the angular surface of rib 8. The valve mechanism is otherwise the same asthat shown in Figs. l, 2 and 3l l In Fig. 5 is shown a still different form of locking device which consists o@ a part 125A which is in the form of a large staple and is inserted into a pair of eyes 19 and 20 so that the horizontal bar of the staple engages the `surface of the rib 8 to maintain the valve closed.`
